BUTTON OR STUD.

SPECIFICATEON forming part of Letters Patent No. 328,565, dated October 20, 1885.

Application filed February 24, 1885. Serial No. 156,695.

To all whom it may concern.-

Be it known that I, GEORGE H. BOWERMAN, a citizen of the United States, residing in Newark, Essex county, New Jersey, have invented certain new and useful Improvements in Buttons or Studs, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

My invention consists in the construction herein shown and described for the post, spring, and center knuckle.

In the drawings, Figure l is a side View of the button with the shoe tilted nearly to one side. Fig. 2 is an edge view of the button with the shoe tilted in the opposite position, ready for insertion in the button-hole. Fig. 3 is a section taken on the line 1 y in Fig. 1; Fig. 4, a plan of the shoe and the center knuckle; Fig. 5, a section through the line as a; in Fig. 8, showing the form of the post and means for attaching the spring. Fig. 6 is a side view, and Fig. 7 an end view, of the post before the spring is attached; and Fig. 8, a side view of the spring.

A is the shoe; B, the front of the button; 0, the center knuckle; P, the post; S, the spring, and a an arm projecting from the shoe to one side of the center knuckle.

The post is of fiat form, provided at one side with ribsf at the opposite edges, between which the spring is laid and clamped by bending the ribs over the edges of the spring, as shown in Figs. 1 and 5. The post is attached to the front at one end, and is provided with a transverse open slot. 7), at the other to receive the center knuckle, which is pivoted movably therein by pin (Z.

The spring is of flat leaf form, with its edges narrowed at one end adjacent to the knuckle, as shown in Figs. 1 and 8, so as to clear the ribs f, and the knuckle is formed with three fiat faces, 0 c and 0, the faces 0 being parallel with the shoe, and the face 0 at right angles thereto. The spring bears alike upon each of these faces when the shoe is turned upon the pin (1, and operates to hold the stud in its normal position when pressing upon the face 0, as shown in Fig. 3. The arm a is attached to the side of the knuckle opposite the face 0, thus leaving one of the faces 0 unobstructed adjacent to the shoe, and affording room for the point of the spring between the knuckle (No model.)

and the shoe. By this construction the shoe may be tilted in either direction for insertion through a button-hole, the spring bearing upon one of the faces 0 in either case, and the view in Fig. 2 showing the position of the shoe and the location of the spring between the same and the knuckle, when the shoe is turned to the right hand of the View that is shown in Fig. 3.

The space between the ribs f upon the post forms a shallow groove, 9, which can be readily formed by pressure between rollers, leaving the ribs f of suitable dimensions to clinch over the edges of the spring, as shown in Fig. 5, and such post may therefore be very cheaply made by rolling in bars of considerable length, which may then be cut into suitable pieces for a single post, and finished by forming the slot 1) and hole for the pin (1.

The spring S is narrowed at one end, as shown in Figs. 1 and 8, to admit such mode of construction for the post, it being much cheaper to cut the spring of such form than to remove the ribs from one part of the post.

I am aware of United States Patent No. 254,087, showing a leaf-spring secured by riveting at one end near the foot of the post and fastened diagonally across a slot in the same to engage a lug upon the shoe, and that many other analagous constructions have been made for a similar purpose. My invention differs, however, from others in the form of the post, the center knuckle, and the spring, and I therefore disclaim the invention shown in the said patent, and any other construction than that specifically shown and described herein.

By my construction the various parts may be very cheaply constructed, and the spring be attached to the post without any rivet or other separate fastenings.

The center knuckle is also of a form that is readily made in one piece with the arm a, the knuckle being square upon three sides, and the arm attached to the fourth side and secured to the shoe by solder in the usual manner.

The construction thus formed differs from that in the patent, No. 254,087, referred to above, not only in the mere form of the post, the knuckle, and the spring, but in affording a tipping movement of the shoe in either direction from its normal position, and thus enabling the user to employ .it with more satisfaction than one in which the shoe can only be tipped in a single direction.

Having thus set forth the nature of my in- 'vention, and distinguished it from others,

2. The combination, with the post 1?, constructed, as described, with groove 9 and ribs f, of the spring S, secured to the post by bending the ribs f and formed. with the end nar- 2o rowed to play between the bent ribs, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

GEORGE H. BOWERMAN.
